UV-curable epoxy acrylate resin with low viscosity and high solid was synthesized by the reaction of epoxy resin,epoxide diluents and acrylic acid.The epoxy acrylates were further modified by maleic anhydride to obtain waterborne UV curable photosensitive resins.The effect of different epoxide-diluents on resin's viscosity was discussed.Furthermore,the effects of reaction conditions such as reaction temperature,the type and mass ratio of catalyst were demonstrated.The optimum conditions of reaction were achieved.The influences of different amount epoxide diluents on the properties of UV-cured film were elucidated.After UV-curing,the performances of coating film were superior.A faster speed under UV curing,a higher grade of pencil hardness and adhesion were achieved.
